The BBC has released new photos from the third season of Happy Valley, "featuring Sarah Lancashire in her iconic role of Sergeant Catherine Cawood for the last time".

Releasing the photos from the final season, the BBC said: "Catherine is pictured with a bloodied nose in the aftermath of a police raid while Tommy Lee Royce (James Norton) - with a radically different look - is seen in his prison cell, alongside first-look glimpses of Catherine's sister Clare (Siobhan Finneran) and teenage grandson Ryan (Rhys Connah)."

The synopsis for the final six episodes reads: "When Catherine discovers the remains of a gangland murder victim in a drained reservoir, it sparks a chain of events that unwittingly leads her straight back to Tommy Lee Royce.

"Her grandson Ryan is now 16 and still living with Catherine, but he has ideas of his own about what kind of relationship he wants to have with the man Catherine refuses to acknowledge as his father.

"Still battling the seemingly never-ending problem of drugs in the valley and those who supply them, Catherine is on the cusp of retirement."

A broadcast date has yet to be announced.
